Loom picker



Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE LOOM PICKER Application April 6, 1932, Serial No. 603,580

4 Claims.

My invention, which relates to loom pickers, has among its objects the provision of improved means for securing the parts of such a device in assembled relation.

The invention however, and the other objects thereof, will be best understood from the following description when read in the light of the accompanying drawing of several illustrative embodiments of the invention, the scope of which latter will be more particularly pointed out in the appended claims.

In the drawing:-

Fig. 1 is a plan of a loom picker and associated picker stick;

Fig. 2 is an elevation, according to Fig. 1, showing a fragment of the picker stick; and

Fig. 3 is a longitudinal section of a modified form of the loom picker.

The loom picker illustrated in Figs. 1 and 2 comprises a strip I of leather which is bent around a filler, the latter comprising the leather strips 3, to form a bunter head 5 and a loop I, which loop forms an eye 9 for receiving the picker stick II.

As shown, one end portion I3 of the leather strip I lies against the lower side of the filler, as viewed in Fig. 1, and is bent upward to form a portion I5 which lies against the side of the filler opposite the picker stick, the strip continuing over the upper side of the filler and extending to the right to form the loop I, the strip then continuing over the portions I3 and I5 thereof to the upper side of the picker where it terminates in the skived portion I'I.

As shown, a pair of fastening members extend through the bunter head for securing the parts in assembled relation. Herein, these fastening members comprise rivets having flat heads I9 and shanks 2|, the exterior surfaces of the rivet heads lying flush with the outer surfaces of the bunter head. The ends of the rivet shanks are preferably welded together while the rivets are under longitudinal pressure .urging them toward each other.

The picker above described may be conveniently manufactured by bending the strip l by use of suitable forms, after which the filler comprising the strips 3- may be inserted, theparts at this stage preferably being cemented together in a form while under pressure to aid in holding them in assembled relation. The holes for the rivets may then be formed, and the pairs of rivets inserted from opposite ends of these holes, the shanks of the rivets being of such length as to permit their ends to be upset, as

indicated at 23, during the welding operation. The rivets may then be subjected to the action of an electric welding machine, say the well known Thompson welding machine, which acts to engage the rivet heads and press the opposite 5 rivets longitudinally toward each other and heat them. The temperature being greatest where the ends of the rivets are in contact due to the higher resistance at this point, said ends will be upset, and, if the rivets are of weldable 10 material, said ends will be welded together. Conveniently the pressure employed is such as to force the rivet heads I9 into the leather, the jaws of the welding machine which contact the rivet heads preferably being of larger area than said heads so as to engage a large extent of the surrounding portions of the leather. As a result of this operation the rivet heads are forced into the leather, and the entire bunter head compressed, and in the finished article the surfaces of the rivet heads are flush with the surrounding surfaces of the leather.

The eye 9 formed by the loop I may be applied to the picker stick by inserting the latter in said eye, after which the picker may be secured to the stick by use of a suitable screw 25.

If desired, instead of welding the ends of the rivets, they may be subjected to sufficient pres.- sure without heating them to expand their ends in one of the leather strips 3, say the center strip, as shown in Fig. 1. This upsetting of the ends conveniently may be formed by using non-weldable material for the rivets and subjecting them to the action of the welding machine as hereinbefore described.

It will be understood that although the ends of the shanks of the rivets are preferably welded together or upset by use of a welding machine which exerts a steady pressure, this pressure if desired can be caused by hammering, or by any other suitable operation which will urge the rivets toward each other in such a way as to produce the desired result.

The loom picker shown in Fig. 3 is exactly similar to that hereinbefore described, except that the filler for the bunter head is in the form of a single layer or block 25 which may be of synthetic material having a leather base, or other material suitable for the purpose.

It will be understood that wide deviations may be made from the forms of the invention herein described without departing from the spirit of the invention.

I claim:

1. A loom picker having a bunter head composed of a plurality of layers of material, and means for holding said layers in assembled relation comprising headed rivets provided with shanks extending into said head from opposite sides thereof, the ends of said shanks being in abuttingrelation at the interior of one of said layers and expanded thereat to increase their diameters for securing the ends of said shanks directly to said layer.

2. A loom picker having, in combination, a hunter head formed of a plurality of layers of leather or the like, a strap for securing said bunter head to a picker stick, said strap having portions at opposite sides of said bunter head, means holding said portions of said strap and said layers in assembled relation under compression comprising headed rivets having shanks extending through said portions of said strap into said bunter head With the ends of said shanks in abutting relation interiorly of one of said layers and thereat welded together, the weld point of said shanks being of greater diameter than the latter for securing said shanks directly to said layer.

3. A loom picker having, in combination, a hunter head comprising layers of relatively resilient material, each transverse half of said head having a plurality of said layers, and means for holding said layers in assembled relation with 5 the layers of each transverse half of said head under compression independently of the layers of the other half and with said halves held under compression relative to each other.

4. A loom picker having, in combination, a 10 bunter head comprising layers of relatively re silient material, each transverse half of said head having a plurality of said layers, and means for holding said layers in assembled relation with the layers of each transverse half of said head 15 under compression independently of the layers of the other half and with said halves held under compression relative to each other, said means comprising headed rivets provided with shanks extending into said head from the opposite go sides thereof with the ends of said shanks in abutting relation and Welded together, the weld point of said shanks being of expanded diameter.
